Particles of light cannot be divided into smaller particles, but if you try to snip off the end of one, instead of shortening it multiplies
In 2026, the hype for artificial intelligence agents is louder than ever before. These semi-autonomous programs can “think” and execute well-defined tasks in areas like customer service and software development, typically using language models (LMs). But fields like medical diagnosis and scientific discovery require them to inquire about a vast range of solutions in uncertain environments which LMs struggle with.
Researchers at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and Harvard University’s School of Engineering and Applied Sciences (SEAS) peered deeper into LMs to understand their main issues in high-stakes settings. Their test: Battleship, a classic guessing game that’s helped cognitive scientists study how humans seek information.
CSAIL and SEAS scholars added a twist by reframing the game around asking and answering natural language questions. In their “Collaborative Battleship” game, one participant is a “captain” who inquires about where hidden ships are, while their teammate plays the “spotter” by responding to those questions in real time.

Because the method does not require a needle, it could offer an alternative for people who are uncomfortable with injections. Researchers also believe it may make large scale vaccination campaigns easier and faster, particularly in settings where traditional injections are more difficult to administer.
Before human testing began, animal studies showed the vaccine could generate strong immune responses against multiple coronaviruses.
Inflammation, especially chronic inflammation, plays a pivotal role in tumorigenesis and metastasis through various mechanisms and is now recognized as a hallmark of cancer and an attractive therapeutic target in cancer. In this review, we discuss recent advances in molecular mechanisms of how inflammation promotes tumorigenesis and metastasis and suppresses anti-tumor immunity in various types of solid tumors, including esophageal, gastric, colorectal, liver, and pancreatic cancer as well as hematopoietic malignancies.
A paper published in Nature Chemistry in May 2025 describes what its authors call the first demonstration of exponential RNA replication by a polymerase ribozyme under conditions that could plausibly have occurred on the early Earth. The work comes from Dr James Attwater and Dr Philipp Holliger at the MRC Laboratory of Molecular Biology in Cambridge, with co-authors at UCL Chemistry.
